358 High-Security Fence, often referred to as Anti-Climb Mesh, is a robust security barrier designed to deter intruders. Its name comes from its precise mesh dimensions: openings of approximately 3 inches (76.2 mm) by 0.5 inches (12.7 mm) and wire thickness of 8 gauge (4 mm). This unique configuration makes the fence nearly impossible to climb or cut through, making it an ideal choice for high security environments such as prisons, military bases and government facilities.
The fence’s strength extends beyond its mesh pattern. The use of high-grade steel and precision welding ensures durability and resistance to physical attack. Proper installation, including the strategic use of sturdy posts and secure fasteners, is critical for optimal performance.
The 358 High-Security Fence can be further strengthened to enhance its protective capabilities with additional security measures such as razor wire or electric fencing. Regular inspection and maintenance are essential to maintain the integrity and effectiveness of the fence.
Flat Steel Reinforced Mesh Fence
Flat Steel Reinforced Mesh Fence is an upgraded version of standard 358 mesh fencing, featuring flat steel instead of round wire for enhanced strength. This robust fence, constructed from cold-drawn flat steel and galvanized wire, can withstand rigorous testing and is ideal for high-security applications. With larger mesh sizes up to 4 meters and reinforced with sturdy columns, it offers exceptional durability. Proven effective in demanding environments, including the Pakistan Airport, this fence provides a superior level of protection.
Features of 358 High-Security Fence
Anti-Climbing: The small apertures of the 358 mesh, measuring 76.2mm by 12.7mm, prevent intruders from gaining a foothold or handhold, making it nearly impossible to climb.
Anti-Cutting: Made from robust 4mm diameter wire, the fence is resistant to cutting by conventional tools such as bolt cutters and wire cutters, enhancing its security.
High Strength: Each intersection of the mesh is welded, ensuring strong joints and high structural integrity.
Durability: The fence is treated with Galfan coating and polymer powder coating to provide excellent corrosion resistance and a long service life.
Visibility: The mesh design allows for maximum visibility, which is crucial for surveillance systems and emergency response.
Common Specifications
Mesh Size: The standard mesh size is 76.2mm by 12.7mm, with wire thickness of 4mm.
Fence Height: Commonly available heights range from 2 meters to 3 meters.
Fence Width: Standard widths include 1.5 meters, 2 meters, and 2.4 meters.
Post Dimensions: Intermediate posts typically measure 80mm by 60mm by 2.5mm, and corner posts measure 80mm by 80mm by 3mm. Posts are spaced at 2.525 meters centers.
Finish Options
Corrosion Resistance: The fence can be treated with various forms of corrosion resistance, including electric galvanizing, hot-dip galvanizing, PVC spraying, and PVC coating.
Color Options: Standard colors include Green (RAL6005), Black (RAL9005), and Yellow (RAL1021). Other colors are available upon request to match specific requirements.
Installation
Mesh Panels to Posts: The mesh panels are attached to tubular steel posts, typically measuring 1-1/2″ by 2-3/8″ or 1-1/2″ by 3″. The panels can be mounted on the face of the posts or between posts using brackets.
Fixing Brackets: Steel fixing brackets are utilized to secure the panels to the front face of the posts. Panels are butt-jointed at each post, secured with double-drilled fixing brackets, and fitted with twin rows of M8 threaded inserts.
